Yes speaking as a doc. In fact a couple of my junior after completing fm residency applied go sport med. So doing their 3 years ast.

As the previous doc mention, fracgp not 100% equivalent to sg mmed. Coz sg mmed here think they so great.

My co ho is now a senior rad resident, from monash, but did HO in Singapore.
In fact i also had co HO from melbourne, now onco ac.

I do not necessarily think aussie grads are less adapted than nus grads in navigating the local system. It is more of intrinsic ability. After a month or two u be fine. I have seen very slow gs HO, myself included. That have to compensate and come at 4am and leave at 11pm post take.
But coz either they ocd, or slow.

If they efficient can come at 6am and leave at 7pm one.

But now residencies more competitive compared to 7 to 8years ago.

At the same time, my current colleague also has consultants that trained in aussie, got their fracp

I think times like this the only scientific way is to look at the stars/astrology/divinity/horoscope. There are no good solutions.
